Description

Technical Field

[0001] This invention relates to the field of architectural engineering technology, and more specifically to an auxiliary tool for architectural surveying. Background Technology

[0002] In construction engineering, surveying is required for buildings. The instrument generally used is a surveying instrument. A surveying instrument is an instrument or device designed and manufactured for surveying operations that integrates data acquisition, processing, and output. It is used for various orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry instruments in the planning, design, construction, and operation management stages of engineering construction.

[0003] Existing surveying instruments generally need to be mounted on a support, which is mostly a tripod. This type of support has a certain leveling function, but its leveling is mostly a manual adjustment structure. After leveling, it is necessary to rely on the instrument's judgment and then perform the corresponding leveling. The leveling is difficult and often takes a lot of time.

[0004] In existing structures, such as the invention patent with patent number 2018222176315, a surveying instrument bracket that is easy to level is disclosed. It includes a support platform and three support rods located below it. All support rods are hinged to the support platform and evenly arranged. A mounting base for mounting the surveying instrument is provided above the support platform. Multiple adjusting screws are provided on the support platform, all vertically arranged and penetrating the support platform. The lower surface of the mounting base has multiple support blind holes corresponding to the positions of the adjusting screws. The upper ends of the adjusting screws extend into the support blind holes. A locking screw is provided on the side of the mounting base, extending from the side of the mounting base into the support blind holes. The mounting base also has a horizontal groove, within which a suitable level is installed. This structure uses adjusting screws for leveling, and the leveling is determined by the tester observing the level, which has a certain degree of error. Therefore, it is necessary to research an auxiliary tool for architectural surveying. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide an auxiliary tool for architectural surveying, which effectively solves the problem that existing leveling structures rely heavily on visual judgment of the level and the use of adjusting rods for leveling, which is greatly affected by human subjective factors and has certain errors.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an auxiliary tool for architectural surveying includes a base, a balance ball, a balance bar, a leveling seat, a working base, and fixing screws; the base has a ball sleeve inside, with a balance ball fitted inside the ball sleeve, and four balance holes arranged in an array on the outer wall of the ball sleeve; the balance bar corresponds to each balance hole and is distributed on the balance ball through the balance hole array; a counterweight ball is provided at the outer end of the balance bar; the bottom of the leveling seat is fixed to the upper center of the balance bar and is in an absolutely horizontal state under the adjustment of the balance bar; a top screw is provided on the outer wall of the ball sleeve; the working base is fitted onto the base at intervals and can sit on the leveling seat; the fixing screw is provided on the side of the working base and can abut against the base to fix the position of the working base.

[0007] Furthermore, a pad is provided at the bottom of the working base, and the pad is adapted to the size of the leveling seat.

[0008] Furthermore, a limiting block is provided at the bottom of the leveling seat, and a limiting groove is provided in the middle of the leveling base. The leveling seat is fitted into the limiting groove by the limiting block.

[0009] Furthermore, the set screw is vertically positioned at the bottom of the ball sleeve and can abut against the bottom of the balance ball to temporarily lock the position of the balance ball.

[0010] Furthermore, the balance hole has a slotted structure, and the balance rod has a round rod structure.

[0011] Furthermore, the working base is provided with clearance holes, and the upper part of the base base is threadedly connected to a lifting screw. A lifting sleeve is fixed on the lifting screw. The lifting screw is spaced within the clearance holes. By rotating the lifting screw, the lifting sleeve can be pressed against the lower part of the clearance holes, thereby lifting the working base. A platform for mounting surveying instruments is provided in the middle of the working base.

[0012] Furthermore, each lifting screw is equipped with a drive wheel at its upper part, and the drive wheels are connected to each other by a belt or chain. An operating lever is installed on one of the lifting screws.

[0013] Furthermore, a triangular bracket is provided at the bottom of the base, and the ball sleeve is fixed to the triangular bracket by a fixing seat.

[0014] The beneficial effects of the above technical solution are as follows: Existing leveling structures often rely on visual observation of the horizontal level and manual adjustment of the adjusting rods, which is cumbersome and prone to errors. This invention first uses the existing triangular support for rough leveling, ensuring the base is basically level. For this rough leveling, the invention employs a ball balance structure for automatic leveling. Structurally, a ball sleeve is installed inside the base, containing a balance ball. Four balance rods extend outward from the balance ball, arranged in pairs. The balance rods are balanced by the fulcrum between the ball sleeve and the balance rods. A counterweight ball is placed at the end of each balance rod, causing the balance ball to automatically level within the ball sleeve. This ensures the leveling seat in the center of the balance ball is absolutely horizontal, thus establishing an absolutely level base. The working base is then fitted onto the leveling seat, thereby leveling the working instrument.

[0015] During operation, the present invention uses the top screw at the bottom of the balance ball to level the balance ball and put it in a temporary fixed state. When the working base is placed on the leveling seat, the fixing screw is used to establish a stable state. Structurally, the present invention can use a handwheel to make the three lifting screws run synchronously, which is simple to operate.

[0016] In a further structure, to facilitate the lifting of the working base, the present invention provides a lifting screw on the base base, and a lifting sleeve on the lifting screw. The lifting sleeve is raised and lowered by using the screw thread, and the working base is further lifted so that it is in a non-contact state above the leveling seat, so that the leveling seat is naturally leveled. Then the balance ball is temporarily fixed to establish a balance reference plane, and then the working base is lowered onto the balance reference plane.

[0017] Therefore, this invention has a novel structure. Based on existing technology, it establishes a rough horizontal foundation and then uses the self-balancing ability of the balancing ball to establish an absolute horizontal plane. Thus, the leveling purpose can be achieved without subjective judgment. The structure is reasonably designed, the leveling operation is simple, and the occurrence of errors is avoided. It provides convenience for people to perform leveling tests and leveling, effectively solves the problem that existing leveling structures require subjective judgment, has high leveling accuracy, avoids the problem of non-standard leveling adjustment caused by insufficient human experience, has high adaptability, and has high market promotion value.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0030] Example 1: This example aims to provide an auxiliary tool for architectural surveying, mainly used to provide a horizontal plane for instrument measurements. During construction surveying, due to uneven ground, it is often necessary to level the equipment after the main structure is fixed. However, existing leveling methods often rely on visual observation or other auxiliary equipment for measurement, and then make appropriate adjustments based on the measurement results to achieve structural leveling. The leveling operation is cumbersome, and due to subjective judgment, it is difficult for the platform to be absolutely level, resulting in errors. Therefore, it is necessary to research an auxiliary tool for architectural surveying.

[0031] like Figure 1-3The image shows an auxiliary tool for architectural surveying, comprising a base 1, a balance ball 3, a balance bar 5, a leveling seat 6, a working base 8, and fixing screws 9; the specific structure is as follows... Figure 1 As shown, the base 1 is located at the bottom and has a hollow structure inside. The upper part is sealed and a notch is reserved. A ball sleeve 2 is set inside the base 1, and a balance ball 3 is fitted inside the ball sleeve 2. The upper notch of the ball sleeve 2 can accommodate at least half of the balance ball structure. Four balance holes 4 are arranged in an array on the outer wall of the ball sleeve 2. Each balance hole 4 is equipped with a balance bar 5 smaller than itself. That is, the balance bars 5 are distributed on the balance ball 3 through the balance holes 4. A counterweight ball 15 is set at the outer end of the balance bar 5. The counterweight ball 15 is used to increase the weight of the balance bar to improve the balance effect.

[0032] In this embodiment, the balance hole 4 is a flat or round hole structure, and the balance rod 5 is a round rod structure. The width of the groove is greater than the diameter of the round rod, so that the balance rod can swing at a certain angle within the groove, thereby adapting to a certain leveling range. Similarly, in implementation, the balance hole can also be a round hole structure, which is larger than the outer diameter of the balance rod and allows it to swing within a certain range. Its design purpose is to allow the balance rod to extend outward and allow it to swing appropriately.

[0033] Structurally, this embodiment utilizes the matching structure of the balance ball 3 and the ball sleeve 2 to achieve a ball hinge structure. At the same time, a counterweight ball structure is set at the end of the balance bar, thereby forming a lever structure with the center of the ball hinge as the fulcrum. The two opposing balance bars 5 mutually restrain each other to keep the balance bars in the same horizontal position. In turn, the four balance bars 5 mutually restrain each other to form a standard horizontal plane. The leveling seat 6 is fixed on the balance ball 3 by a base that is always perpendicular to this plane, so that the leveling seat 6 is in an absolutely horizontal state.

[0034] In this embodiment, the bottom of the leveling seat 6 is fixed to the upper center of the balance ball 3 and is in an absolutely horizontal state under the adjustment of the balance bar 5; the upper center of the balance ball 3 is explained in this embodiment as being parallel to the plane where the four balance bars are located, and structurally it is fixed to the balance ball 3 by the base, with its center point passing through the center of the ball, and the four balance bars also passing through the center of the ball.

[0035] Meanwhile, in this embodiment, a set screw 16 is provided on the outer wall of the ball sleeve 2; in the specific set screw structure, such as Figure 9 As shown in the diagram, the set screw 16 is vertically positioned at the bottom of the ball sleeve 2 and can rest against the bottom of the balance ball 3 to temporarily lock the position of the balance ball 3. Of course, it can also be fixed to the side. The purpose of this setting is to lock the balance ball by resting against it, so as to temporarily maintain the balanced state and avoid increasing the unbalanced load after the working base is seated.

[0036] In this embodiment, the balance ball can rotate freely inside the ball sleeve. The leveling seat, balance bar, and balance ball are symmetrical in structure. When the base 1 is not horizontal, each balance bar will force the balance ball to level due to its own weight, similar to a balance scale structure, thus providing an absolute horizontal reference for the device. In this embodiment, the standard horizontal surface is fixed temporarily, and then the working base is placed on it.

[0037] After the balance ball 3 is temporarily fixed, the working base 8 is placed on the leveling seat 6. At this time, the balance ball 3 is in a horizontal state. In order to achieve the whole purpose, in this embodiment, the working base 8 is fitted on the base base 1 at intervals and can sit on the leveling seat 6, thereby providing a certain amount of clearance for the angle of the leveling seat 6. After the working base 8 is stable, in this embodiment, the fixing screw 9 is used to finally stabilize the working base. Specifically, the fixing screw is set on the side of the working base and can be pressed against the base base to fix the position of the working base.

[0038] To further improve structural stability, this embodiment includes a pad at the bottom of the working base 8, which is adapted to the size of the leveling seat 6. A limiting block 19 is provided at the bottom of the leveling seat, and a limiting groove 18 is provided in the middle of the leveling seat 6. The working base 8 is fitted into the limiting groove by the limiting block. In practice, the limiting block 19 and the limiting groove 18 have angular structures, such as polygonal structures. After adaptation, they are in a limited state. When the limiting block 19 and the limiting groove 18 are adapted, the leveling seat 6 and the pad surface of the working base 8 can be made to fit together, ensuring the leveling of the working base 8 and the leveling seat 6.

[0039] As an independent structure, the above embodiment can be used by setting a triangular support 17 at the bottom of the base 1, and the ball sleeve 2 can be fixed to the triangular support 17 by the bottom fixing seat 7. First, the existing triangular support 17 is used to perform appropriate rough leveling so that the base 1 is basically in a horizontal state. On the basis of the rough level of the base 1, the ball balance structure is used for automatic leveling. The balance rods 5 are arranged in pairs, and the balance ball 3 and the ball sleeve 2 are balanced by the fulcrum between them. The counterweight ball 15 is arranged at the end of the balance rod 5 so that the balance ball 3 is automatically leveled in the ball sleeve 2, so that the leveling seat in the middle of the balance ball is in an absolutely horizontal state, thereby establishing an absolutely horizontal base surface. Then, the working base is matched and placed on the leveling seat, so that the working instrument is in a horizontal state.

[0040] During operation, the structure is basically leveled using a triangular support. Then, the working base is detached from the leveling seat to prevent it from bearing load on the leveling seat. After the leveling seat is naturally released, it will automatically level itself under the action of four balance bars. After it comes to rest, the leveling seat is in an absolutely horizontal state. The balance ball is fixed with a set screw to temporarily fix it. Then, the working base is placed on the horizontal leveling seat, and the state of the working base is locked with a fixing screw. This embodiment can achieve the leveling purpose without subjective judgment. The structure is reasonably set, the leveling operation is simple, and the occurrence of errors is avoided, providing convenience for people to achieve leveling tests.

[0041] Example 2: This example has a structure that is basically the same as that of Example 1. The difference is that, based on the lifting structure of the working base, this example further describes the working base.

[0042] In this embodiment, the working base 8 is provided with a clearance hole 10, which is a circular hole in structure. The upper part of the base base 1 is threaded with a lifting screw 13, which is a circular rod structure. A lifting sleeve 20 is fixed on the lifting screw 13. The lifting sleeve 20 is a disc-shaped structure larger than the clearance hole 10. The lifting screw 13 is spaced inside the clearance hole 10. By rotating the lifting screw 13, the lifting sleeve 20 can be pushed against the lower part of the clearance hole 10, and the working base can be lifted. The middle part of the working base is provided with a platform 11 for installing surveying instruments. As one implementation method, the lifting screw 13 is a single drive structure.

[0043] In a further structure, each of the lifting screws 13 is equipped with a transmission wheel 14 on its upper part. The transmission wheels 14 are connected to each other by a belt or chain 12. An operating rod 22 is provided on one of the lifting screws. The operating rod 22 is used to drive one of the lifting screws 13 to rotate. During its lifting and rotation, it will synchronously drive the other two lifting screws to lift synchronously.

[0044] In this embodiment, the operating lever drives one lifting screw to rotate, and the belt or chain synchronously drives the other lifting screws to rotate. By utilizing the threaded relationship between the lifting screws and the base, the lifting sleeve is raised or lowered during rotation, thereby raising or lowering the working base.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The structural concept is to use a ball balance structure to establish a standard horizontal plane, first separating the working base from the leveling seat, and then placing it on the leveled leveling seat. Any modifications, equivalent substitutions, and improvements made within the principle of the present invention, such as changes to the lifting structure of the working base and the shape of the balance bar, should be included within the protection scope of the present invention.
